Miscellaneous
=============

     This is a copy of HEA5345A.TXT except that it is labeled for the MEX
extended mission (MEX-M-RSS-1-ENT-V1.0). The previous report was HEA5341A.TXT.

  Anomalies
  ---------

     There was no signal in the data collected at DSS 65 on day 331.  There
had been problems with spacecraft and ground configurations during this time
period; but occultations 20 hours earlier and 6 hours later were successfully
captured at DSS 14.  This occultation was collected using a VSR (very similar
to the RSR, but intended for VLBI use).

     The DSS 63 X-band carrier levels on days 338 and 343 are modulated by an
approximately +/-0.5 dB square wave with period 42 seconds.  The S-band
carrier level is also modulated but at an amplitude that is barely
discernible. This suggests a cause in either the ground or spacecraft
antenna.  There are 0.5 dB changes in X-band carrier level on day 334 at
DSS 65 and on day 340 at DSS 14; but these are 1 or 2 time events lasting no
more than a minute.

     The customary "power line" spurs are scattered through all of the X-band
spectra (except day 331) because of the high signal levels.
